Application filed January 31, 1923. Serial No. 616,216.

To all whom it may concern Be it known that I, ANTONIO CArPAnr- ANOA, a subject of the King of italy, resid ing at Braddock, in the county of Allegheny and State of Penn lvania, have invented o certain new and useful Improvements'in Mechanically-Operated Cribs, of which the following i a specification.

This invention relates to improvements in mechanically operated cribs. V An important object of the invention is to provide mechanical means for rocking av crib to eliminate the tiring manual performance of the same operation, and whereby considerable time will be saved the attendant for performing other necessary duties.

A further object of the invention is the construction of eflicient, durable mechanism for performing the above mentioned operation.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, 7

Figure 1 is a top plan view with a of the crib broken away to more clearly show the mechanical operating means carried by the crib supporting frame,

Figure 2 is a vertical sectional view taken on line Ill-II of Fig. 1,

Figure 3 is a fragmentary vertical sectional View taken on line III-11]: of Fig. 1,

Figure 4 is a fragmentary vertical sectional view taken on line IVIV of Fig. 1, Figure 5 is a fragmentary vertical sectional ,view taken on line VV of Fig. 1,

Figure 6 is a fragmentary vertical sectional view taken on line VIVI of Fig. 1, and f Figure 7 is a detail sectional view showing a portion of a resilient means employed for returning the crib to a vertical position after the rocking operation'has stopped. i In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, thenumeral 1 designates a skeleton frame that is provided for properly supporting the crib 2 and having transverse brace bars 3, 4 and 5 for supporting the operating mechanism to be de portion scribed hereafter. It is to be understood that the crib 2 may be constructed inany desired manner and provided with perpendlcular support-mg rings or eyes 6' that are carried by the opposite ends of the crib and positioned centrally thereof for pivotally engaging supporting pins 7 carried by the opposite ends of the skeleton frame 1.

The operating mechanism employed for rocking the crib 2 is supported, as-stated above, by the transverse brace bars 3, 4 and 5, and consists of a driven shaft 8 that is suitably-journaled in the bearing members 9 and 10 that are carried by the brace bars 3 and 4 respectively. This driven shaft 8 is provided with apulley wheel 11 that is rigidly secured to the end 12 and is further providedwith a pinion 13 that is positioned centrally between the said brace-bars 3 and 4. There is further provided a relatively long shaft 14 that'extends longitudinally of the skeleton frame 1 and is suitably journaled in the bearing members 15,16 and 17 carried by the brace bars 3, 4 and 5' respectively. This longitudinally extending shaft 14 is positioned substantially upon a vertical plane with the pivot pins 6 carried by the skeleton'frame 1 and is provided with a gear 18 that is positioned between the bracebars 3 and 4 and constantly in mesh with the pinion 13 for affording operative connection with the driven shaft 8. Referring particularly to Fig. 4, there is shown an eccentric block 19 that is suitably keyed to the longitudinal shaft 14 and is loosely engaged'by the splitc'ollar 20 that is secured thereto by the clamping bolts 21, the split collar 20 is provided with a. boss 22 that is adapted for receiving one end of a rod 23 threaded therein. The outer end of this rod 23 is pivotally connected, as at 24, to an arm 25 carried by the stub shaft 26. Referring to -Fig. 1, it will beseen that this shaft 26 is suitably journaled, as at 27, to the transverse brace: bar 5 and is further provided with an arm 28 that is rigidly connected to. I

the outer end of this shaft and best shown in Fig. 6. Pivotally connected, as at 29, to the upper end of the arm 28 is a link 30 that is pivotally connected at its. opposite end '31- to a lug 32 that is rigidly secured, as at'33,

to one of the bottom slats-'34 carried by'the crib 2 and best shown'in Fig.1. i x The means employed for returning the crib to a vertical position. after the rock mechanism has been shut off, is shown in (16-.

tail in Figsfi, 5and '7'. Referring tol 'igs. 3 and 7 there is shown an eccentri'c bloclc 35 that is suitably keyed to the longitudinal shaft 1% and is loosely engaged by the split collar 36 that is retained in position by means of the clamping bolts 37, as shown.

Secured to the upper edge of the splitcollar 36 is an'eye member 38'tha-t is connected to acoil spring 39 which extends to an eye member 40 carried by one of the bottom slats of the crib 2. In Fig. there isshown a col.- lar or ring member 4L1 that is loosely mounted upon the end 42 ofthelongitudinal shaft 1 and is provided with anarml3 that is connected by the 5 nin 44; and e e 45 with one of thebottom slats of the crib; I

The driving power for operating this rocking'mechanism einbodiesan electric inotor aL-G lthat is properly supported and se- 3 ands.

cured to the transverse brace bars controland "has an electric switch 47 for ling the supply of'current thereto. The ar-- mature shaft of the motor 46 is provided with a smallpulley wheel 48 that is opera tively connected to the pulley wheel 11 car- .ried by the driven shaft 8, by the belt 4921s shown.

The operation. of the device is as follows Upon turning on the current to the electric motorlfi, the driven shaft 8 will be rotated by means of the belt 459 operatively connected with the pulleywheels ll 4:8,

and the pinion 13'will drive the gear 18 for.

rotating the longitudinal shaft L1. The rotation of this shaft let will impart movement to the rod 28, through the eccentric bloclf 19 'and split collar 20 for'actuating the linlr 30 to cause the cradle 52 to rock upon the supporting pins 7 carried by-the skeleton'frame 1. Uponshutting off the current to the motor t6 the rocking of the cradlewill naturally stop, the spring 44, carried by the arm a3, and the spring 39, carried by the collar 36. will sition. This pull will be snfficientto operate the mechanism for allowing the cradle to be returned to its desired IBSUYIQ position.- It to beunderstod'that the form of this invention herewith shown and. described is to' be talienas apreferred example of the same, and that various changes in the shape.

size, arrangement of parts may be issorted to w thout departing from the spirit of the invention or the scope of the subjoined claims.
